SHUTTLE.

Application filed May 12, 1913. Serial No. 766,962.

To all whom itmag concern:

Be it known that we, JEAN B. DAUDELIN and Eosnsn H. DAUDELIN, citizens of the United States, residing at Fall River, county of Bristol, and Commonwealth of Massachusetts, have invented certain new and use ful Improvements in Shuttles, of which the following is a specification.

This invention relates to hand threading shuttles and particularly to a-guard for the threading eye of such a shuttle.

The dethreading tendency due to the writhing and twisting action of the thread during the run of the shuttle is well recognized in the art and it is the object of our present invention to provide simple and efficient means, capable of'application to any shuttle of ordinary type for overcoming this diiliculty. Most of the thread guards heretofore devised have been expensive and such as have come into practical use have for the most part been of the bushing type. WVe have found that the bushing is unnecessary and in the form of our invention which has proved best adapted to practical use we'construct the guard of wire.

In the accompanying drawings we have shown our wire eye guard which consists of a bar through the eye, transverseof the shuttle and above the entry of the thread-.

ing passage to the eye and terminating in a spaced loop returned across itself and, the threading slot, applied on the shuttle in its preferred form.

The invention will be more fully described in the specification which follows, throughout which and the drawings above referred to, like reference numerals are employed to indicate corresponding parts.

- In the drawings, Figure 1 is a plan view of the threading end of the shuttle equipped with our invention, Fig. 2 is a longitudinal view, partly in section of the same, Fig. 3 is a view of the thread guard removed from the shuttle and Fig. f is a side elevation of the threading end of the shuttle.

The shuttle body 1 may be of any construction having a bobbin chamber 2 in which is located a bobbin 3 on which is wound a thread T. I

From the forward end of the bobbin chamber 2 leads the eye 4: to which the threading slots 5 and 6 connect. The slot 5 is in the form shown diagonally disposed with respect to the longitudinal axis of the shuttle and so sawed as to develop a curve Specification of Letters Patent.

on the shuttle top. At one side of the opening between the eye 4 and the chamber 2 a pin 11 is usually driven for strengthening the tongue of wood formed in the shuttle body 1 by the two slots 5Vand 6. This pin forms also a smooth guard and wear post. over which the thread T runs when All this is usual and standard construction andonly necessarily considered in connection with the guard whichwe will now describe. This guard comprises a relatively straight shank 13 extending transversely of the shuttle body and arranged above the plane ofentry of the threading passage 6 into the eye 4 and clenched at its freeend to lock the guard in place. The opposite endof, said shank is bent into a loop let'crossing itself below the level of said shankbut leaving space between its overlapped portions and extending at 15 on the side of the threading slot opposite to the direction of its original deflection from said transverse shank. The spiral thus formed substantially conforms to the contour of the delivery end of the eye and comprises the downwardly bent loop 1& which extends at a slight slope across the plane of entry of the threading passage '6 into the eye. This loop follows theouter wall of the threading eye and as it approaches its downward bend 14 is depressed to provide a portion 15 lying slightly below the plane of entry of the threading slot 6.

This portion 15 crosses the portion 14 below the level of said transverse shank but leaves a space between its overlap sufficiently large to permit the entrance of the thread from the slot 6. Near this overlap the portion 15.

is deflected upwardly to provide a portion 15 overlying the plane of entry of the threading, slot 6 and disposed at an acute angle thereto so as to deflect the thread downwardly and into the confines of the loops 14: and 12. This portion 15 terminates on the side of the threading slot 6 opposite to the direction of its original deflection from the transverse shank 13.

On the part 15 is formed an inwardly. I

be observed that the portion 15 deflects the a thread from the passage 6 into the space left between the overlap of the looped parts 14 and 15 and thus over the transverse bar 13, from which it feeds in a direction transversely of the shuttle. Any tendency of the thread to run back into the slot 6 is met and prevented by the vertically disposed loop 14 Any tendency of the thread to escape by an upward movement is met by the relatively horizontal portion 15 of the guard which portion lies slightly below the plane of entry of the threading slot 6 but in substantially parallelism with said slot. The thread is therefore held against escape by any path other than its true path of delivery and feeds from the eye in a uniform even manner.

It will be apparent to any one skilled in the art and familiar with the-dethreading tendency due to the writhing and twisting action of the thread during the run of the shuttle, that our improved threading guard will efiectively prevent this escape of the thread. It will also be apparent that our construction does away with the usualbushing while at the same time is capable of 1 application to any shuttle of the ordinary type in general use.

Various modifications in the bending of the guard, in the material and construction thereof, in the exact disposal of the same, and generally in the details of form and arrangement may obviously be made all without departing from the spirit of our invention if within the limits of the appended claims.

What we, therefore, claim and desire to secure by Letters Patent is:

1. In combination with a shuttle having a delivery eye and a threading passage lead- 1 ing thereto, a thread guard arranged in said eye and comprising a transverse bar disposed therein above the plane of entry of the threading passage into the eye and having its outer end bent into a loop crossing itself below the level of said transverse bar but leaving a space between its overlap opposite the plane of entry of the threading passage and terminating on the side of the thread slot opposite to the direction of its original deflection from said transverse bar.-

2. In combination with a shuttle having a delivery eye and a threading passage leading thereto, a thread guard arranged in said eye and comprising a transverse bar set in the shuttle body and disposed therein across the body of the shuttle above the plane of entry of the threading passage into the eye and having its outer end bent into a loop in substantial conformity to the delivery end of said eye and crossing itself below the level of said transverse bar but leaving a space between its overlap opposite the plane of entry of the threading passage and terminating in a point set in the side of the thread slot opposite to the direction of its original deflection from said transverse bar and over the plane of entry of the threading passage into the eye.

In testimony whereof we affix our signatures in presence of two witnesses.
